The Lowdown

Alright, this is Rusty. Let's have a look at what's happening for us here.

First off, I gotta be straight with you: the next 16 days are looking pretty grim for Kennebunk Beach. We're stuck in a real flat spell. The water's sitting around 68°, which is a touch warmer than you'd usually expect for mid-August, but that's about the only thing that's out of the ordinary. The wave energy is just nowhere to be found for most of the run, with combined energies barely ticking over, like a measly 7 (moderate energy) on the first Sunday morning. That's not enough to get excited about.

We start off on Sunday the 16th with tiny, weak swell – 0.7ft to 1ft from the SSE – and it's crossed up by a light breeze. Not surfable. Monday the 17th brings a bit more size, up to 4ft from the S, but it's accompanied by light rain and a cross-onshore wind that'll chop it all up. That lasts into the week. By Tuesday the 18th, we finally get some clean conditions with a light offshore from the NE in the morning, but the swell is still only 3ft from the SE and short-period at 6 seconds, so the energy is weak (59). Not worth paddling out for.

The pattern just keeps repeating: tiny swells, wrong winds. There’s a brief moment on Tuesday afternoon the 18th where the combined energy hits 216 (moderate energy) with 4ft SE swell and an 8-second period, but it's under a light cross-shore. It’s the best of a bad bunch, but it’s still not good. For a sheltered spot like this, we really need a clean offshore window with some push, and we just aren't getting it.

Looking further out, the second week is more of the same. We finally see a long-period groundswell on the 24th, with a 12-second period from the SE, but it's only 1ft – no power behind it. There's a tease on the afternoon of the 27th of August, with glassy conditions and a 2ft SE swell carrying a combined energy of 233 (moderate energy), which has more potential, but it's paired with a risk of thunderstorms. That's about the only day I'd even bother checking the cam, and even then, it's a longshot.

Honestly, if you're in the area and you're desperate, check that Thursday the 27th afternoon for a possible glassy session on the tiny, weak waves. The swell direction from the SE is on the outer edge of what works for this spot, which prefers ENE, so don't expect much shape. Otherwise, you're looking at a 16-day stretch with no real standouts. The setup looks more interesting for a kite surfer than a paddle surfer most days, with the onshore winds and small chop.

For the whole 16-day window, I can only point to that Thursday afternoon the 27th as a maybe. It's not great, but it's all we've got. Keep an eye on the sky, 'cause the glassy conditions might just give you a fun little window on a longboard.

Rusty.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
